# Which of the following is correct about carbon fiber?

$(a)\;\text{low molecular mass} \\ (b)\;\text{high abrasion resistance} \\(c)\;\text{high electrical conductivity} \\ (d)\;\text{high hygroscopicity}$

Carbon fibres are highly resistant to thermal shocks and fracture , have low molecular mass , high abrasion resistance, high elecrical conductivity, low hydroscopicity.
They are not affected by the biological changes and their is no corrosion.
Hence d is the correct answer.
